Chess variants do not work on iOS

Hello, I have been playing on the Chess.com website for some time and have now installed the app for iOS. But I don't know how to play chess variants there. Does anyone know how to do this? Thanks

Just click on the magnifying glass icon, just bellow the board, to play possible variants of any given position you might be playing. Another window will open with different icons at the tool bar bellow the board. Once you have figured out what you want to do, just click on the top left X icon to go back to the playing board and do your move. Pretty simple

Other than 960, variants are not natively supported on the apps.

You can use the method posted above but it's easier to log into mobile browser instead and access them that way.
